The Moderate Resolution Imaging Spectroradiometer ( MODIS ) on NASAs Terra satellite captured this true-color image of the ruggedly beautiful northeast coast of Greenland on July 10, 2004. Clouds swirl over the dark blue Greenland Sea in which chunks of ice float. In the top center of the image, a horn of ice, called Flade Isblink, extends east away from the coast. A dark smudge of wind-blown gravel is visible near the base of the ice sheet. Strong winter winds blow the gravel from the land out over the sea. Now, in July, the winter snow has melted, making the remaining gravel visible on top of the ice. Source: Jeff Schmaltz, MODIS Rapid Response Team, NASA/GSFC
